Breeding for Resistance to Groundnut Virus Diseases at ICRISAT Center

At ICRISAT Cent�r in India germplasm screening and resislance breeding projects are being carried out to produce varielies with resislance to buJ necrosis disease caused by tomato spotted wilt (TSWV), peanut mollie virus (PMV), peanut stripe virus (PSlV), and peanut clump virus (PCV) diseases. Breeding for resistance to groundnut rosette virus (GRV) disease is being done at the SADCC/ICRISAT Center in Chitedze, Malawi, in southern Africa. TSWV has been reporteJ in groundnut from many counlries and is currenlly economically important in India and the USA. It is lransmitled by 'I'liril's I'"/III; in India and by Frtlllklilliella occidelltal; and F. /USCII in the USA. TSWV is nol �eed­ transmitted. Utilizing a field-screening technklue developed al ICRISAC more than 7000 germplasm accessions of cullivated groundnut and 42 wild Arachis
